VALVE Specification of Letters Patent.

Patented July 23, 1907.

Application filed July 19, 1906. Serial No. 826,873.

To all whom it may concern:

Be it known that I, HENRY O. MONTGOMERY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Valves, of which the following is a specification.

This invention is a valve adapted for steam and water pipes, cocks and faucets, and also especially suitable for steam radiators.

The object of the invention is to provide an improved quick opening valve. This valve may be opened or closed with very small movement, and it is so constructed that the parts can be readily removed or replaced. The valve seat, especially, can be easily replaced, as will more fully hereinafter appear.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a longitudinal section and Fig. 2 is a sectional view on the line 22 of Fig. 1.

Referring specifically to the drawings, 10 indicates the angular valve casing, having an inlet 10 and an outlet 10 and a neck 10 through which the valve stem extends. The neck is large enough to allow the passage of the valve disk and seat therethrough.

The valve seat consists of a disk 11 which sets on a shoulder 10 in the inlet branch, and said disk has lugs 11 which fit in notches 10 in said shoulder so that it cannot turn. The valve seat is held in place by the pressure of the valve stem and its disk. Said seat has a central circular hole 11 and a circular row of holes 11 around the same.

The valve stem is indicated at 12 and it projects at its lower end through the central hole 11 in the valve seat and has an outwardly-extending circular disk or flange 12" which is provided with holes 12 adapted to register with the holes 11 of the valve seat. The upper face of the valve seat is conically depressed or ground and the meeting face of the valve disk 12* is accordingly ground tightened as desired.

13 which screws in the threaded upper end of the neck, against the Washer. The plug holds the valve stem down and the valve disk holds the seat in place, and by manipulating the nut the valve can be loosened or By removing the nut the valve stem and disk can be pulled out and the valve seat piece lifted out. Since the seat is not an integral part of the casing, this makes repairs thereof easy and inexpensive.

The valve is opened or closed by turning the stern which throws the holes 11 and 12" in or out of register and consequently opens or closes the valve. When four holes are provided, as shown, the valve will open or close, full, by a one-eighth turn, which makes a very quick action.

The valve seat 11 and ring 12 are preferably made of non-corrosive, non-metallic self lubricating material, such as a composition of black lead and fullers earth, molded to proper shape. The conical parts described prevent leak and obviate the use of a stufling box.

I claim:

1. A valve comprising a casing having a neck, a de tachahle seat therein opposite the neck, a turning stem extending through the neck and seat and having a valve disk bearing against the seat and a conical disk within the neck, said seat and valve disk having openings which may be registered, a ring within the neck, having a conical depression in which said conical disk fits, and a plug screwed into the neck against the ring therein, the neck being'of suITicient size to allow the passage of the valve disk and seat therethrough, when the plug is removed.

2. A valve comprising a casing having therein a valve seat with a conical depression and a central bearing and an opposite ring with a conical depression, and a valve stem extending through the ring and fitting at its inner end in said bearing and having oppositely disposed conical disks fitting respectively against the seat and the ring.

3. A valve comprising a casing having therein a valve seat and an opposite ring, said seat and ring being made of a composition of black lead and fullers earth, and a valve stem having oppositely disposed disks bearing against said seat and ring.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HENRY C. MONTGOMERY.
